The Pinzu-Timed Super Explosion is I-Pin's most destructive ability.
It is activated when she is extremely shy (as seen with Kyoya Hibari), or extremely mad (as seen with Lambo). After it is activated, a special countdown begins and appears on the middle of her forehead. When the countdown gets from nine to one, she will start to glow and then become a human bomb.
I-Pin likes to hold onto someone when she explodes, shown once when she held onto Tsunayoshi Sawada. Her explosion can create a small crater with its destruction, but she is unharmed by her own explosion. Adult I-Pin had this ability sealed away by her master, Fon, but can be reactivated with the words "Broccoli Monster" (ブロッコリーの化け物, Burokkorī no Bakemono?).
- The symbols on I-Pin's forehead are the numbers from the Dots suit in Mahjong. Pinzu is the Japanese term for the suit.
- This technique is ranked 36th out of 816 special techniques, as told by Futa.
